FLYING-OFF REEL WITH ROLLERS TRUING A WIRE FED THERETO Filed Dec. 13, 1963 4 Sheets-Sheet 4 2 E. 5 INVENTOR BY "W W United States Patent 2 Claims. ((11. 72-308) The present invention relates to a flying-off reel with rollers truing a wire fed thereto and constitutes a further development of the flying-01f wheel disclosed in the copending patent application, Serial No. 219,225, filed August 24, 1962; now Patent No. 3,182,477, granted May 11, 1965.

A flying-off reel for the discharging of rough wires has been disclosed, wherein a gripping member, the movement of which in the pulling direction of feeding is controlled, is disposed in front of discharging rollers truing the wire, which gripping member receives the end of the material to be rolled and advances the latter in the direction of feeding, whereby the head of the gripping member is rotatably mounted on a linearly displaceable slide, the gripping member being formed with a mouth, which is radially open towards a wire ring and receives clampingly the end of the wire.

The control of the gripping member, that means, its rotation required for the advancing and inserting of the end of thewire, is brought about by a leg controlled by the marginal edges of an angular slot. The curved-shaped end of the wire freely projecting from the gripping member engages thereby a supporting wire slide guide and is freely forming bent linearly by the occurring vending forces.

This bending into a straight direction of the starting end of the wire leads to difiiculties in connection with different wire sizes and materials.

It is, therefore, one object of the present invention to provide a flying-off reel with rollers truing a wire fed thereto, wherein the truing of the curved-shaped wire section is performed by means of a tool.

It is another object of the present invention to provide a flying-off reel with rollers truing a wire fed thereto, wherein the head of the gripping member is provided with a pressure finger pointing in the direction of the discharging rollers for the straightening of the end of the wire which engages an anvil disposed in front of the discharging rollers.

Hereby not only an overloading of the clamping point of the wire in the mouth of the gripping member is prevented, rather a pressing of the wire into a straight line is brought about, whereby the performance of the material of the wire concerning elasticity or flexibility is maintained within favorable limits. The accuracy of the straightening and the safe insertion resulting therefrom are thus ensured.

It is still another object of the present invention to provide a flying-01f reel with rollers truing a wire fed thereto, wherein a simple, reliable design is brought about, which conforms particularly to the pressure forces of the finger and wherein the rotary and displacement movement of the head of the gripping member is controlled by an arm mounted on the axis of the gripping member, the free end of the arm, entering between adjustment abutments, is secured during the linear displacement of the slide of the gripping member.

With these and other objects in view, which will become apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawings, in which:

FIGURE 1 is a front elevation of a flying-off reel;

"ice

FIG. 2 is an end view of the flying-01f reel disclosed in FIG. 1;

FIG. 3 is a front elevation of the gripping member designed in accordance with the present invention and shown at an enlarged scale;

FIG. 4 is a longitudinal cross-section of the gripping member;

FIGS. 5 to 8 disclose in a front elevation the manner of operation of the gripping member, and in particular the starting position of the latter for clamping the wire,

the starting of the truing operation of the wire, the fin ished truing and the insertion of the wire between the discharging rollers, and the gripping member in its returned starting position, respectively.

Referring now to the drawings, and in particular to FIGS. 1 and 2, the flying-01f reel comprises a box-like stand 1 including a front wall 1 which is equipped with a slot 17 disposed above a drum 3 within the plane of discharging rollers 7 and 8 mounted in the box-like stand. A gripping member having a head 11 is mounted in the stand 1 and projects through the slot 17. The head 11 of the gripping member has a shaft 14 (FIG. 4), which is rotatably mounted in a slide 15 longitudinally displaceable in guides 16 of the front wall 1'. The gripping member 11 is equipped with two cross blocks 11' and defines with the latter two mouth formations 12 between which a tappet 13 is guided for clamping the wire end 30'. The tappet 13 can be advanced and withdrawn, respectively, by means of a threaded spindle 13'.

The slide 15 can likewise be reciprocated by a threaded spindle 20 which is, preferably, driven by a motor (not shown).

The gripping member 11 is equipped with a pressure finger 35 pointing in the direction of the discharging rollers 7 and 8 for the straightening or truing of the wire end 30 which sits on an anvil 10 disposed in front of the discharging rollers 7 and 8. Furthermore, an arm 36 (FIG. 4) is rigidly mounted on the shaft 14 of the gripping member 11, the free end of the arm 36 being equipped with a roller 37 and entering a space defined between adjustment abutment members 38 and 38', which are provided in a displaceable holder 39 (FIG. 3) disposed in the stand 1.

A threaded setting spindle 40 is rotatably, but axially immovably mounted in the box-like stand 1 and serves the purpose of displacing axially the holder 39 by means of an inner thread complementary to the thread of the setting spindle 40.

The limitation of the displacement of the slide 15 is assured by limit switches 41 and 41', disposed in the boxlike stand within the path of movement of the slide 15, and by which switches 41 and 41' the motor drive of the threaded spindle 20 can be stopped and reversed, respectively.

The operation of the described apparatus is performed in the following manner:

As can be ascertained from FIG. 5, in the basic position of the gripping member 11, the wire end 30" is pulled into the mouth 12 of the gripping member 11 by means of a cable line 33 and is clamped tight by means of the tappet 13. Then the slide 15 of the gripping member 11 is put into motion in the direction towards the discharging rollers 7 and 8 by means of the threaded spindle 20. Due to the unchanged position of the holder 39, the arm 36 swings out, since the shaft 14 of the gripping member 11 carrying the arm 36 is likewise moved away. The roller 37 steps out accordingly from the adjustment abutments 38 and 38' onto the edge of the holder 39, on which edge it is guided during the remainder of the displacement stroke. A fast shifting of the pressure finger 35 into a substantially horizontal position is, thereby, brought about.

The bent wire end 3%) is swung by means of the rotation of the gripping member 11, so that the point of the wire is supported by the anvil 10 (FIG. 6). Thereafter the finger 35 presses onto the wire and straightens it out, whereby the wire successively engages the straight bottom face of the pressure finger 35. By means of the successive advancement of the gripping member 11 in the direction towards the discharging rollers 7 and 8 the point of the wire, which has been bent straight, is thereafter inserted between the rollers 7 and 8, as shown in FIG. 7. Hereafter the discharging rollers 7 and 8 are moved towards each other and the tappet 13 of the gripping member 11 is withdrawn, so that the wire is released, and the slide 15 with the gripping member 11. is returned intoits starting position (FIG. 8). Upon the arrival of the slide 15 in its rear position, the roller 37 engages the abutment 38 and turns the pressure finger 35, as well as the gripping member 11 into the required inclined position. The gripping member 11 is now prepared for the next discharging following thereafter.
